Literal ripples in the fabric of space-time, called gravitational waves, were created by the merger of two massive black holes 1.3 billion years ago. The Laser Interferometer Gravitational-Wave Observatory (LIGO) on Earth detected them on Sept. 14, 2015, and scientists evaluated their findings and put them through the peer review process before publicly disclosing the landmark discovery today. Physicists working with a powerful observatory on Earth announced Thursday that they have finally detected ripples in space and time created by two colliding black holes, confirming a prediction made by Albert Einstein 100 years ago….

Here is an interesting article on how Russian scientists are planning to tweak their ICBMs (intercontinental ballistic missiles) to target near-earth objects (NEOs), according to a report by news agency TASS. The news came from Sabit Saitgarayev, the leading researcher at the Makeyev Rocket Design Bureau. The projectiles could be aimed at meteorites measuring 20-50 meters in size. A meteorite is a chunk of debris that can originate from a sun-orbiting asteroid, and that survives the trip through the atmosphere to reach Earth’s surface.

The scientists plan to test their missiles on the asteroid 99942 Apophis, which Saitgarayev believes may pass “dangerously close” to Earth in 2036. There is a general consensus as to this expected close encounter, though NASA has “effectively ruled out the possibility” of an impact.
